FREDERICK HEISER, OF BALTIMORE, MARYLAND.

POLISHING COMPOUND.

SPECIFICATION forming part of Letters Patent No. 261,922, dated August 1, 1882,

Application filed J nne 16, 1882. (No specimens.)

To all whom it may concern:

Be it known that I, FREDERICK HEISER, a

.citizen of the United States of America, re-

siding at Baltimore, State of Maryland, have invented certain new and useful Improvements in Polishing Compounds, of which the following is a specification.

This invention relates to an improvement in polishing compounds adapted to produce a most beautiful polish on articles of metal, glass, &e.; and it consists in the peculiar combination of materials hereinafter described and claimed.

The ingredients and proportions are as follows: coal, two parts; red paint, two parts ocher, one part; loam, one part.

In preparing the compound I take the coal and burn it to ashes, and then grind and sit't it. The other ingredients are simply dried, ground, and sifted, and then the whole is thoroughly mixed. Great care is taken, however, in grinding and sitting all the materials to eliminate everything likely to scratch the object being polished.

The term red paint. is applied to a mineral dug in the Thirteenth District in Baltimore county, Maryland, which is largely used as a roofing-paint. The loam and ocher are taken from my farm in the Fifth District of Anne Arnndel county, in the same State, and both are peculiarly fitted for use in a polishing composition, as they contain large portions of ammonia, and by their use it is believed that one of the best compounds ever made for pol- Witnesses:
